Wear something quick

Not wanting to waste anymore time. You find some clothes that would by easier to run with. The selection is very limited tough. You picked up a simple top, a skirt and a pair of flats. You then run out of your house to go search for the black-wearing person. Last time you see them were at your room's window, which was at the back of your home. They may have already run out by now, but it might still be worth checking out.
